A plurality of radial arms 11 ismountedas In its more detailed nature the invention at 12 upon the shaftand in the'disclosure resides in the provisionof a casing having an heremade each arm comprises a pair of 7 opening just large enough to enableremoval spring wires suitably spaced by a pair of I60 of a single bottleof milk, and a novel turnspacer plates 13, the said wires being flaredtable-like mechanism Within he Casing, haV- and shaped at their outer orfree endsfasat 14 ling individual arms to receive" milk bottles, toreceive a milk bottle neck.
